Khar Lake (; ) is located in Khovd Province in western Mongolia's Great Lakes Depression.
It is also known as Ha-la Hu, Hara Nuur, Har Nuur, Khara Nur, Khar Nuur, and Ozero Kara-Nor
It should be distinguished from the similarly named Khar Lake (Zavkhan), another lake further east in Mongolia.
It is part of a group of lakes that were once part of a larger prehistoric lake that disappeared 5,000 years ago as the region became drier.
Some sources are using different Khar Lake statistics values:
Khar Lake has a single inflow - Chono Kharaikh Gol river, which creates a river delta.
Khar Lake has a connection to Dörgön Nuur south of it.
